There was enough disk space (almost another gig more). So it's probably
some buffer manager problem. Is that the postgres buffer manager or is it a
Linux one?

Are you able to duplicate that problem? All I did was to turn off
autocommit and start inserting.

Wow, that's cool.. Should be enough for everyone. I can't imagine anybody
making 4 billion statements without committing anything, not even politicians!

What's WAL? Is postgres going to be faster than MySQL? That would be pretty
impressive- transactions and all. Woohoo!

Hope it doesn't stand for Whoops, All's Lost :).

Cheerio,
